Question

Factorize x4+7x2y2+16y4
4 n 2 are squares

Answer 1

Answer:

(x²+3y²)(x²+4y²)

Step-by-step explanation:

x⁴+(3y²+4y²)x²+3y²×4y²

=(x²+3y²)(x²+4y²)

Answer 2

Answer:

So, we get

x2 + x - 6

Now we write it As :

x2 + 3x - 2x - 6

x ( x + 3 ) - 2 ( x + 3 )

( x - 2 ) ( x + 3 )

So we have factors

x4 + x 3 - 7x2 - x + 6 = ( x - 1 ) ( x + 1 ) ( x - 2 ) ( x + 3 )
